Petunia plant named ‘Petrosena’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Petrosena’ characterized by its trailing, outwardly spreading and mounded plant habit, freely branching habit, freely flowering habit, single flowers that are rose in color, and good garden performance.

Latin name of the genus and species of the plant claimed: Petuniahybrida.

Varietal denomination: ‘Petrosena’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Petuniaplant botanically known as Petunia hybrida and referred to by thecultivar name ‘Petrosena.’

The new Petunia is the product of a planned breeding program conductedby the inventor in Enkhuizen, Netherlands. The new Petunia cultivar isfreely flowering with trailing and spreading plant habit and attractiveleaf and flower coloration.

The new Petunia originated from a cross-pollination made by the inventorin August 2000 of a proprietary selection of Petunia hybrida identifiedas code number ‘A998’ not patented, as the female, or seed parent, witha proprietary selection of Petunia hybrida identified as code number‘Y942,’ not patented, as the male, or pollen parent. The new Petunia wasselected as a single plant from the resulting progeny of thecross-pollination in a controlled environment in Enkhuizen, Netherlandsin June 2001.

Asexual reproduction of the new cultivar by terminal vegetative cuttingssince June 2001, in Enkhuizen, Netherlands has shown that the uniquefeatures of this new Petunia are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Petrosena’ have not been observed under allpossible environmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, light intensity anddaylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Petrosena.’ These characteristics incombination distinguish ‘Petrosena’ as a new and distinct cultivar:

-   -   1. Trailing, outwardly spreading and mounded plant habit    -   2. Freely branching habit    -   3. Freely flowering habit    -   4. Single flowers that are rose in color    -   5. Good garden performance

In side-by-side comparisons conducted in Enkhuizen, Netherlands, plantsof the Petunia named ‘Petrosena’ differed from plants of the femaleparent selection in the following characteristic:

-   -   1. Plants of the Petunia named ‘Petrosena’ have rose flowers        whereas flowers of the female parent selection are rose/purple.

In side-by-side comparisons conducted in Enkhuizen, Netherlands, plantsof the Petunia named ‘Petrosena’ differed from plants of the male parentselection in the following characteristic:

-   -   1. Plants of the Petunia named ‘Petrosena’ and the male parent        selection differed in flower size. The flowers of the Petunia        named ‘Petrosena’ are smaller than the flowers of the male        parent selection.

DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearanceof the new cultivar, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Petunia.

DESCRIPTION OF THE NEW CULTIVAR

The observations and measurements describe plants grown in Enkhuizen,The Netherlands, practice circumstances indoor in hanging baskets ofdiameter 25 cm during the early Spring with day temperatures rangingfrom 14 to 16° C., night temperatures ranging from 12 to 14° C. Plantsused for the photographs and description were about 10 weeks fromplanting rooted cuttings.
